Yes insane maybe but the quality would be superior to what you will get from the V500. Think they use dedicated film scanners not flatbed scanners...

I have the Epson V700 and the quality of the prints I have done from E6 scans dont come close to the prints I got from photolabs to be honest.

If you want to print from scanned colour film on a flatbed scanner I would recommend shooting colour negative film. Slide film doesn't seem to scan as well as modern negative film on a flatbed I have found...
